Bionic flexible arm drive type submersible

The invention relates to a bionic flexible arm drive type submersible and belongs to the technical field of diving robots. The bionic flexible arm drive type submersible comprises a watertight body shell, a control unit and a power source unit which are installed in an inner cavity of the watertight body shell, and a buoyancy adjusting unit and a power unit which are controlled by the control unit; the power unit comprises more than three flexible drive arms installed at the tail end of the watertight body shell; and each flexible drive arm comprises a flexible arm body and an actuator installed in the flexible arm body and used for driving the flexible arm body to bend and deform, and each actuator comprises an electrical deformation element. The flexible arm bodies driven by the electrical deformation elements are adopted as the flexible drive arms, so that the motion mode of an octopus is simulated, noise generated in the operation process is effectively reduced, the invisibility ofthe whole submersible is
